Hello, and thank you for letting us help you with your automotive question. Is the check engine light on when the engine is running? How many miles are on the vehicle?
yes the check engine light is on. 100150 miles
Okay. You need to start by having the vehicles computer scanned for codes. You can have this done for free at most auto parts stores. Come back here with the codes and I will let you know what is going on. It sounds like you either have a severe vacuum leak or a problem with the fuel system.
